For a while I was looking for varios approaches in making a replica of sonic the hedgehog game physics in flash.
There are the cheap ones and very complex ones.
I seen the engine where the character is resting on two dots and turns based on position of these two dots as if they were wheels.
Another one is where the tilt has the invisible zones and when character hit them it turns to a particular angle. It looks a bit choppy but that works. (in fact the old genesis had this happening when you moved slow)
And another one I seen where all physics are done by math. But the script was impossible to read X (
After all I realise that a Hittest is a complete crap when a deal comes to speed and physics. will guarantee a failure when dealing with walls, or floor.
Just wonder if anyone seen a more practical+ reliable physics engine. : )
